The Ultraviolet Line Spectrum Of The Soft X-Ray Transient Xte J1118+480: A Cno-Processed Core Exposed, C. A. Haswell, R. I. Hynes, A. R. King, K. Schenker Jan 2002

The Ultraviolet Line Spectrum Of The Soft X-Ray Transient Xte J1118+480: A Cno-Processed Core Exposed, C. A. Haswell, R. I. Hynes, A. R. King, K. Schenker

Faculty Publications

We compare ultraviolet (UV) spectra of the recent soft X-ray transients XTE J1118+480 and XTE J1859+226. The emission line strengths in XTE J1118+480 strongly suggest that the accreting material has been CNO processed. We show that this system must have come into contact with a secondary star of about 1.5 M⊙, and an orbital period ∼ 15 h, very close to the bifurcation value at which the nuclear and angular momentum loss time-scales are similar. Subsequent evolution to the current period of 4.1 h was driven by angular momentum loss. In passing through a period of 7.75 h the secondary …

Linear Optics And Projective Measurements Alone Suffice To Create Large-Photon-Number Path Entanglement, Hwang Lee, Pieter Kok, Nicolas J. Cerf, Jonathan P. Dowling Jan 2002

Linear Optics And Projective Measurements Alone Suffice To Create Large-Photon-Number Path Entanglement, Hwang Lee, Pieter Kok, Nicolas J. Cerf, Jonathan P. Dowling

Faculty Publications

We propose a method for preparing maximal path entanglement with a definite photon-number N, larger than two, using projective measurements. In contrast with the previously known schemes, our method uses only linear optics. Specifically, we exhibit a way of generating four-photon, path-entangled states of the form [Formula Presented] using only four beam splitters and two detectors. These states are of major interest as a resource for quantum interferometric sensors as well as for optical quantum lithography and quantum holography. © 2002 The American Physical Society.

Quantum Path Distributions For High-Order Harmonics In Rare Gas Atoms, Mette B. Gaarde, Kenneth J. Schafer Jan 2002

Quantum Path Distributions For High-Order Harmonics In Rare Gas Atoms, Mette B. Gaarde, Kenneth J. Schafer

Faculty Publications

We present quantum path distributions of high-order harmonics produced by rare gas atoms interacting with an intense 810 nm laser field, obtained by numerical integration of the time-dependent Schrödinger equation within the single active electron approximation. We find that the distributions are sensitive to the atomic potentials, and differ from the distributions predicted by the strong field approximation. We demonstrate that these differences can lead to significant differences in the time-frequency behavior of the harmonics produced in a macroscopic nonlinear medium. © 2002 The American Physical Society.

Acetylcholinesterase Mediated Susceptibility Of Soldiers And Workers Of Formosan Subterranean Termite (Isoptera: Rhinotermitidae) To Chlorpyrifos., Sridevi S. Gatti, Gregg Henderson, Yehia A.I. Abdel-Aal, Sanaa A. Ibrahim Jan 2002

Acetylcholinesterase Mediated Susceptibility Of Soldiers And Workers Of Formosan Subterranean Termite (Isoptera: Rhinotermitidae) To Chlorpyrifos., Sridevi S. Gatti, Gregg Henderson, Yehia A.I. Abdel-Aal, Sanaa A. Ibrahim

Faculty Publications

Target site studies were undertaken to examine the difference in susceptibility of Formosan subterranean termite, Coptotermes formosanus Shiraki, workers and soldiers to chlorpyrifos. Workers exhibited significantly greater acetylcholinesterase activity per insect than soldiers (118.63 +/- 48.51 versus 47.98 +/- 22.59 mOD/min/insect equivalent). Likewise, enzyme activity (mean +/- SD) per milligram of protein was greater in workers than soldiers (440.30 +/- 267.43 versus 311.53 +/- 149.83 mOD/min/mg protein). The enzyme of soldiers was more sensitive to the acetylcholinesterase (AChE) inhibitors eserine and chlorpyrifos-oxon than that of workers. The I50s of chlorpyrifos-oxon were 2.66 and 4.59 nM for soldiers and workers, respectively, …

Numerical Methods For The Simulation Of Dynamical Mass Transfer In Binaries, Patrick M. Motl, Joel E. Tohline, Juhan Frank Jan 2002

Numerical Methods For The Simulation Of Dynamical Mass Transfer In Binaries, Patrick M. Motl, Joel E. Tohline, Juhan Frank

Faculty Publications

We describe computational tools that have been developed to simulate dynamical mass transfer in semidetached, polytropic binaries that are initially executing synchronous rotation upon circular orbits. Initial equilibrium models are generated with a self-consistent field algorithm; models are then evolved in time with a parallel, explicit, Eulerian hydrodynamics code with no assumptions made about the symmetry of the system. Poisson's equation is solved along with the equations of ideal fluid mechanics to allow us to treat the nonlinear tidal distortion of the components in a fully self-consistent manner. We present results from several standard numerical experiments that have been conducted …

Stability Properties Of A Formulation Of Einstein's Equations, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio Jan 2002

Stability Properties Of A Formulation Of Einstein's Equations, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio

Faculty Publications

We study the stability properties of the Kidder-Scheel-Teukolsky (KST) many-parameter formulation of Einstein's equations for weak gravitational waves on flat space-time from a continuum and numerical point of view. At the continuum, performing a linearized analysis of the equations around flat space-time, it turns out that they have, essentially, no non-principal terms. As a consequence, in the weak field limit the stability properties of this formulation depend only on the level of hyperbolicity of the system. At the discrete level we present some simple one-dimensional simulations using the KST family. The goal is to analyze the type of instabilities that …

Semiparametric Maximum Likelihood Estimates Of Spatial Dependence, R. Kelley Pace, James P. Lesage Jan 2002

Semiparametric Maximum Likelihood Estimates Of Spatial Dependence, R. Kelley Pace, James P. Lesage

Faculty Publications

We semiparametrically model spatial dependence via a combination of simpler weight matrices (termed spatial basis matrices) and fit this model via maximum likelihood. Estimation of the model relies on the intuition that bounds to the log-determinant term in the log-likelihood can provide penalties to overfitting both the level and pattern of spatial dependence. By relying on symmetric and doubly stochastic spatial basis matrices that reflect different weight specifications assigned to neighboring observations, we are able to derive a mathematical expression for bounds on the log-determinant term that appears in the likelihood function. These bounds can be conveniently calculated allowing us …

In The Dark Woods I Lost My Way, Debbie Kupinsky Jan 2002

In The Dark Woods I Lost My Way, Debbie Kupinsky

LSU Master's Theses

When I had journeyed half our life's way, I found myself in a shadowed forest. For I had Lost the path that does not stray Ah, it is hard to speak of what it was, That savage forest, dense and difficult, Which even in recall renews my fear: So bitter-death is hardly so severe! Dante Alegheri Inferno Canto 1 Dante's passage refers to the losing of a spiritual path, but for me it refers to the destruction of the past, memory and self. My work deals with the loss of the past and the burdens of memory. It deals with …

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu Jan 2002

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu

LSU Master's Theses

Wireless sensor network (WSN) has been attracting research efforts due to the rapidly increasing applications in military and civilian fields. An important issue in wireless sensor network is how to send information in an efficient and adaptive way. Information can be directly sent back to the base station or through a sequence of intermediate nodes. In the later case, it becomes the problem of routing. Current routing protocols can be categorized into two groups, namely table-drive (proactive) routing protocols and source-initiated on-demand (reactive) routing. For ad hoc wireless sensor network, routing protocols must deal with some unique constraints such as …

Address Code And Arithmetic Optimizations For Embedded Systems, J. Ramanujam, S. Krishnamurthy, J. Hong, M. Kandemir Jan 2002

Address Code And Arithmetic Optimizations For Embedded Systems, J. Ramanujam, S. Krishnamurthy, J. Hong, M. Kandemir

Faculty Publications

An important class of problems used widely in both the embedded systems and scientific domains perform memory intensive computations on large data sets. These data sets get to be typically stored in main memory, which means that the compiler needs to generate the address of a memory location in order to store these data elements and generate the same address again when they are subsequently retrieved. This memory address computation is quite expensive, and if it is not performed efficiently, the performance degrades significantly. In this paper, we have developed a new compiler approach for optimizing the memory performance of …

Spaced-Retrieval Effects On Name-Face Recognition In Older Adults With Probable Alzheimer's Disease, Karri Sikes Hawley Jan 2002

Spaced-Retrieval Effects On Name-Face Recognition In Older Adults With Probable Alzheimer's Disease, Karri Sikes Hawley

LSU Master's Theses

Six older adults with probable Alzheimer’s disease (AD) were trained to recall a name-face association using the spaced-retrieval method. We administered six training sessions over a two-week period. On each trial, participants selected a target photograph and stated the target name, from eight other photographs, at increasingly longer retention intervals. Results yielded a positive effect of spaced-retrieval training for name-face recognition. All participants were able to select the target photograph and state the target’s name for longer periods of time within and across training sessions. A live person transfer task was administered to determine whether the name-face association, trained by …

A Descriptive Study Of At Risk Mothers' Interactions With Their Children, Vicky Lynn Poston Jan 2002

A Descriptive Study Of At Risk Mothers' Interactions With Their Children, Vicky Lynn Poston

LSU Master's Theses

The purpose of this study was to describe the home environment and nature of mother-child interactions of low-income African-American mothers. The subjects included eight mother-child dyads. All of the mothers were single, African-American and working toward a G.E.D. Their age ranged from 17-30 years of age. Their children ranged in age from 24-67 months. A home visit and a mother-child play session that was collected at the children’s child care center were utilized to collect the data. The findings from the current study were consistent with the literature reviewed in that most of the mothers produced a decreased speech rate, …

Culinary Confusion: Using Osteological And Stable Isotopic Evidence To Reconstruct Paleodiet For The Ocmulgee/Blackshear Cordmarked People Of South Central Georgia, Bryan D. Tucker Jan 2002

Culinary Confusion: Using Osteological And Stable Isotopic Evidence To Reconstruct Paleodiet For The Ocmulgee/Blackshear Cordmarked People Of South Central Georgia, Bryan D. Tucker

LSU Master's Theses

The Ocmulgee Big Bend and Lake Blackshear regions of Georgia have diverse uplands and lowlands, rich in different types of food. Archaeological investigations have shown Late Woodland-style ceramics and artifacts extending up to the Middle Mississippian Period in these regions. Archaeologists have proposed the people of this region did not adopt maize agriculture or a Mississippian subsistence or cultural pattern during the Early Mississippian Period. This study tests this hypothesis with osteological and isotopic data from burials recovered from the Cannon site (9Cp52) and osteological data from the Telfair Mound site (9Tf2). Isotopic data demonstrate clearly that these people were …

The Origin Of Peruvian Professional Militarism, Mariella Reano Jan 2002

The Origin Of Peruvian Professional Militarism, Mariella Reano

LSU Master's Theses

The process of professionalization initiated by the Peruvian army in 1896 under French influence did not withdraw the military from political involvement. On the contrary, as the process of professionalization advanced, the army developed a “professional militarism,” that is, military political participation for reasons based on the institution’s professional ethos. The Peruvian army had traditionally claimed a broad military jurisdiction including extra-military roles. French instructors reinforced such claimed incorporating a broad military jurisdiction into the army’s professional ethos, which justified military coups during the twentieth-century as well as the Revolutionary Government of the Armed Forces (1968-1980). Historians Frederick M. Nunn …

The Role Of Personal Characteristics In International Mediations, Joshua Paul Galliano Jan 2002

The Role Of Personal Characteristics In International Mediations, Joshua Paul Galliano

LSU Master's Theses

This paper presents research on the influence of psychological factors on the outcome of mediation attempts. The research utilizes a base-line model as proposed by Bercovitch, where mediator strategy and mediation outcome result from antecedent contextual inputs and the current mediation process. In addition to these established factors, relevant psychological variables are tested through the Med97 dataset. The case list consists of mediation attempts determined by the involvement of a single mediator and a single negotiator for each side, which allows for the investigation of the effects of the mediator’s and the negotiator’s psychological characteristics. The psychological characteristics investigated in …
